Problem with RS232

[Naiade]

Hi everybody, hope you can help me.

I have a hex compiled with the CCS 3.127 and works ok but I need to change some part of the code and I am using the last one (3.221) and I have a big problem ...

I'm working with a GSM modem and receiving some call I look for "\r\nRING\r\n" but sometimes I just received the \r o \r\n o a little bit more but it seems like the message doesn't arrive ...
someone has got this problem ? Is it a parameter I have to change in the new CCS

Thx for your help.

I add ther parameters I use

#USE RS232 (BAUD=9600, XMIT=PIN_C6, RCV=PIN_C7, PARITY=N, BITS=8)

thx again

I put you the code to see if you see something strange.

#INCLUDE <18F452.h>
#FUSES XT,WDT128,WDT,PUT, NOLVP, NODEBUG
#DEVICE ADC=10
#INCLUDE <string.h>
#INCLUDE <stdlib.h>
#INCLUDE <math.h>
#USE delay(clock=3579000)
#USE RS232 (BAUD=9600, XMIT=PIN_D6, RCV=PIN_D7, PARITY=N, BITS=8,STREAM=SETUP) (this a second RS232 emulated with others I/O pins)
#USE RS232 (BAUD=9600, XMIT=PIN_C6, RCV=PIN_C7, PARITY=N, BITS=8) (this is the modem RS232

Char GetFromRX () {
char data;
if (RXItems > 0)
{
data = *RXInicio;
RXInicio ++;
if (RXInicio > &ColaRX[MAXCOLA-1]) RXInicio = &ColaRX[0];
RXItems --;
return (data);
}
else return(0);
}

#INT_RDA
void Receive (){
char data;
data = getc();

if (RXItems == MAXCOLA) error_fatal();

if (RXItems < MAXCOLA)
{
*RXFinal = data;
RXFinal ++;
IF (RXFinal > &ColaRX[MAXCOLA-1]) RXFinal = &ColaRX[0];
RXItems ++;
}
}


void main()
{

disable_interrupts(GLOBAL);
restart_wdt();
setup_counters(RTCC_INTERNAL, WDT_ON);
setup_wdt(WDT_ON);
restart_wdt();

set_tris_a(0b101111);
set_tris_c(0b11000000);
set_tris_e(0b011);
set_tris_d(0b10000000);


while (TRUE)
{
if (( a=GetfromRX() ) != 0) {recmes[i++]=a;lcd_putc(a);}

if (( i>2 ) && (recmes[i-1] == '\n') ) (LOOKING FOR THE \r\n\ring\r\n)
{
recmes[i]=0;
i=0;
if ( strcmp(recmes,ring) == 0) TAKETHECALL();
}
}
